ATTACHMENT FOR ANVILS.

SPECIFICATION forming part of Letters Patent No. 400,361, dated March 26, 1889.

o Application filed January 26, 1889. Serial No. 297,645| (No modell) To all whom it may concern:

Be it known that l, BENJAMIN E. ROBINSON, of Lyn, in the county of Leeds, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Attachments for Blacksmiths Anvils; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, which represents a perspective view of an anvil provided with my improved'attachment.

My invention has for its object to provide an anvil with an attachment that can be bodily attached and removed without requiring special work on the anvil before the attachment can be applied, Sl-ld attachment being adapted for holding horseshoes while being sharpened, and for other uses.

My invention consists of an attachment comprising a yoke to encompass the tail end of the anvil, the ends of the yoke provided with a screw to clamp the same to the sides of the anvil, a post integral with the yoke at one side of the anvil, a bent arm or lever pivoted horizontally to the top of the post, and provided at the front end with a cam or key engaging the anvil to force the opposite end of the lever to hold the horseshoe against the tail of the anvil, as will be hereinafter more particularly described.

A is the anvil to which the attachment is applied, and such attachment is suited to the size of the anvil, and constructed so as to be bodily or integrally applied, and as such capable of removal.

B is a yoke rectangularly bent to form three sides and encompass the rear end of the anvilthe ends of said yoke provided with ascrew,

b, by which the yoke is clamped to opposite sides of the anvil.

G is a post integral with the yoke at one side of the anvil, and said post supports a lever, D, sleeved on the top of the post to move pivotally in a horizontal plane. The rear end of lever D is bent outwardly, upwardly, and horizontally, so that the rear end will be slightly offset from and parallel to the side of the anvil. The opposite end of said lever is provided with a horizontal slot, in which is pivoted a cam or eccentric, d, or provided with a vertical notch, in which is a wedge-shaped key, d, in contact with the anvil to throw the opposite end of the lever toward or from the side of the anvil, whereby a horseshoe or other article placed interveningly'of the lever and anvil will be held fast, as in a vise, by tightening the cam or key while the calk is being sharpened or the article undergoing shaping. Preferably the lever, intermediately of the cam or wedge and its pivot-center, is curved, as at d and tempered .to act as a spring, whereby the horseshoe orother article will be held more rigidly than were the lever unyielding.

I claim as my invention- A11 attachment for blacksmiths anvils, comprising a yoke, B, provided at the ends with a clamping-screw, b, and having a post, 0, a horizontal lever, D, sleeved pivotally on said post, and provided with a cam or key at one end to force the opposite end sidewise toward the anvil when the yoke is attached, as set forth.
